I like Grey's - much less ridiculous than ER, though I liked the first seasons of ER as well. It was annoying how bad the research was in ER concerning the world outside the US - I'm sure the medical stuff was well researched and that's what I was watching it for, but as soon as anybody or anything outside their immediate frame of cultural reference was introduced it was a lot like some middle schooler's vision of the Kingdom of Ruritania... Sadly it's mostly relationship stuff in Grey's these days, which I tend to fast-forward through. And sex, ditto. I've never watched Private Practice, but I'm afraid I found the final episode before Addison moved away and joined the crew in wherever it was (California?) kind of boring, so I haven't been particularly tempted to look for it. Just not my kind of series, I guess.
